I used polyshades minwax product on my unfinished wood floor at the suggestion of the paint department at Walmart. The floor looks awful, about 400 sq ft. Now I am reading that it is not recommended for floors. But also read where some people have used it on floors. I am going to look at it in the morning but I am not happy with the way it turned out and I am sick over this. Any suggestions?

(FYI the pics are of boards just laid down and not nailed yet) I'm working with a friend and he said we suggested we put a board perpendicular at the end of flooring. There is another room adjacent to the floor current being installed. I am either going to put carpet in the next room but I am leaning more towards the same hard wood floor instead. It seems to running the board perpendicular would serve no purpose either way because I'm going to need a transition strip which would give the same effect. Is there any purpose in going with a board running perpendicular at the end? I actually don't like the look. If it's only for looks then I'll probably go without it.
